“…In this case, 38% of tested sheep were found to have a positive ELISA result, while 7% were found to be positive based on nested PCR testing of vaginal swabs. These findings suggest that Q fever may be still be real problem in sheep in this region of the world [41]. Studies have also revealed C. burnetii to be an important agent causing abortion in sheep and goats in Ethiopia [31,10].…”

Introduction and Objective. Abortion can occur in sheep, among others, in response to bacterial infection. The present article reviews the latest reports on the various economic and health consequences for the herd, other animals and humans. Review methods. Two independent reviewers searched in PubMed and Google scholar (any date to September 2021) for studies concerning bacterial abortion in sheep. Keywords for the search strategy were: bacteria, sheep, and abortion. Papers were reviewed for scientific merit and relevance as well as for current information. Brief description of the state of knowledge. In the reviewed literature, much attention was paid to infections by Brucella spp., Campylobacter spp., Coxiella burnetti, Listeria spp., and Salmonella spp. As the presence of these bacteria varies according to region, any differential diagnosis should consider the most common pathogens in a given area. It also should be noted that most of the described pathogens have zoonotic potential and, as such, it is extremely important to observe safety rules when assisting in delivering births and when dealing with stillbirths. Conclusions. Identification of the etiological agent seems to be a key factor in the management of abortions, especially in flocks where their numbers appear to be increasing; this is needed to manage and control disease in the flock, and to protect humans and other animal species on the farm. Most studies use molecular methods as diagnostic tools, mainly PCR, and use both foetuses and placenta as research material.

“…(2019) reported the first confirmed C. burnetii induced abortion in a doe in Tamil Nadu using molecular assay. In Indian settings, surveillance‐based studies have been carried out in recent past from different parts of the country in small and large ruminants pertaining to organized (Dhaka et al ., 2019), semi‐intensive (Gangoliya et al ., 2019), and backyard settings (Sahu et al ., 2018; Keshavamurthy et al ., 2019; Shome et al ., 2019; Leahy et al ., 2020), gaushalas (Kumar et al ., 2019a), slaughterhouses (Pradeep et al ., 2017; Yadav et al ., 2019). Livestock reared under ‘organized farming’ systems are fed in the same barns, particularly in the commercial livestock rearing.…”

“…Usually, wide variation has been observed regarding the infection rate in animals depending on the locally prevailing epidemiological factors such as population size of reservoirs, and managemental activities. The occurrence of C. burnetii determined using molecular and/or serological assay(s) in large ruminants ranged from 0.97% in Tamil Nadu and Puducherry (Pradeep et al ., 2017) to 29.91% in Uttar Pradesh (Dhaka et al ., 2019); nevertheless, in small ruminants, it ranged between 1.60% in Assam (Leahy et al ., 2020) to 38.50% in Jammu and Kashmir (Gangoliya et al ., 2019). Besides, the pathogen has also been detected from the faeces of wild ranging birds (Das et al ., 2013).…”

“…However, several risk evaluation‐based studies, conducted in the recent past have provided an insight into the possible risks and transmission factors that play a key role. Studies conducted across the countries have indicated a significant association of the pathogen in ruminants with a history of reproductive disorders as compared to the seronegative ones (Vaidya et al ., 2010; Das et al ., 2014; Gangoliya et al ., 2019; Shome et al ., 2019). Important reservoir species associated with C. burnetii were identified to be sheep (Gangoliya et al ., 2019), goats (Sahu et al ., 2018), buffaloes (Shome et al ., 2019) and cattle (Dhaka et al ., 2019).…”

Summary Coxiellosis or Q fever is an important global occupational zoonotic disease caused by one of the most contagious bacterial pathogens – Coxiella burnetii, which ranks one among the 13 global priority zoonoses. The detection of C. burnetii infection is exhibiting an increasing trend in high‐risk personnel around the globe. It has increasingly been detected from foods of animal origin (including bulk milk, eggs, and meat) as well as tick vectors in many parts of the world. Coxiellosis is reported to be an important public health threat causing spontaneous abortions in humans and potential reproductive failure, which would result in production losses among livestock. Further, comprehensive coverage of the reports and trends of Q fever in developing countries, where this infection is supposed to be widely prevalent appears scarce. Also, the pathogen remains grossly neglected and underreported. Moreover, policymakers and funding agencies do not view it as a priority problem, especially in the Indian subcontinent, including Sri Lanka, Bhutan, Pakistan, Nepal, Bangladesh and Maldives. Here, we review the occurrence and epidemiology of the disease in a global context with special emphasis on its status in the Indian subcontinent.
